Application filed March 6 Be it known that I, S'rErANus NIELSEN,

:ithe. borough of-Brookl'yn, cit of New York,

. j in the county of Kings an State'of New.

.Q-York, have invented certain new and useful "improvements in Type-Writin Machines,

of which the'following is a speci cation.

My invention relates particularly to meansfor arresting the rotative movements of the platen so as to predeterminethe extent of its forward movement and the extent of itsbackward movement as. is sometimes desirable when doing condensed record work.

. The main object of my invention is to provide .a sim le and convenient construction,

for this an otherclasses of work.

To these ends my invention consists in the features of construction and. combinations 20 and arrangements of parts all as will be hereinafter more fully describedand particularly pointed out in'the appended cla ms. In the accompanying drawings, Figure. l is a side view partly in section of a Monarch typewriter Wlih my invention embodied t ereini Fig. 2is a partial plan view of the same.

lator. A r r a v A platen shaft '20 passes through the platen, throu through the sidebars 4 and 5 and at its ex wheels 21 and'22, said hand-wheels being securely fastened to the 'endfl of said shaft by screws'23, and the platen being secured to the'shaft through thescrew 24.

common to the Monarch typewriterand the parts now;to be describe are new parts. Projectmgrightward from the right-hand 26 which are preferably secure to said end bar by being threaded thereinto as indicated a slide bar 29 which is slotted 'at 30 .to embrace the cylindrical portion 31 of a shouljdered screw32 whose,shank 33 is threaded into a-tapped hole 84 in the stud 26. said shouldered rtion of a screw 36, the threaded shank 0 which engages a tapped hole 37 to or supported by the carriage and in a way to enable the bar to he slid longitudinally at right"angle's to the axis ofthe platen, or to and fro transversely of the carria e. 1' The bar 29 isrovidedwith a nger'piece 38 and is ,form'e with a square opening des ignated by the numeral 39 to receive part of lalocking' or holding contrivance This oomprises an angular lever 40 vertically pivoted at 41 u on a plate 42' which 'is' secured tothe .bar 29 y screws 43 which enter tapped-holes 'sists of a bifurcated portion 45, til hrou h which thepivot 41 passes, said 1pi ot a so passing through an eye in. the p ate-42)"a finger pieced?) adjacent thefingerdplece 38, an an arm 47 carryi a'p'in 48 a a pass in and-.out'of a ho e at.49.

These studs 25 and 26 support slide bar is lso slotted at 35 to embrace the 44in the bar 29. .The'angular lever-'40 con- The pin is adapted also to pass into a hole at 50 in a keeper 51 which is slotted at 52 to fit upon the shoulder or neck '53 at one end of the screw stud 25, and the keeper isheld 5 thereupon by the same screw 36 which conmeets the bar 29 to the stud 25, the keeper being arranged between the body of the stud and the inner side of the bar. When the barisin itsforward position the pin 48 enga es the holes 49 and 50 and the bar is' thus l'clied in its forward position. When the pin is withdrawn from the keeper by pressing upon the finger piece 46 the bar 29 may be slid rearwardly a short distance and may be held in this position by the end of the pin '48 engaging a depression 54 in the keeper and in the rear. of the hole 50. The pin is pressedtow'ard'the keeper by a spring 55 arranged-between the finger pieces 38 and 46. Toward the rear end of the-bar is a stud 56 having two shoulders 57 and 58 and three diameters, the end of the-stud terminating in a threaded portion 59. The stud is preferably riveted to ,thc'bar as shown at 2 16.0. iMounted on the larger diameter or body of the stud '56.is,a toothed wheel or spur gear 61. Uponthe smaller diameter is fitted acollar or sleeve 62, the inner side of which bears against the shoulder 57, thus holding the .wheel 61. properly inposition upon its bearingQon the stud.. Tl1e collar 62 is fiattened on diametrically opposite sides as at 63 and is perforated and threaded to receive two pivot screws 64. Mounted upon the fiattened faces 63of the collar is a stop device 65, comprising a branched portion 66, which provides arms or side bars 67 adapted to be seated upon the faces 63. The arms or bars 67 are formed with perforated ears 68 through whichihe screws 64 pass after the stop device has been fitted upon the collar, the screws operating to hold the stop device upon the collarin 'a manner such that the stop device and the collarma y be rotated together about the stud and also such that the stop device may have an independent pivotal or vibratory movement about the screws 64,

as will hereinafter more fully appear.

The collarand the stop device are held upon" the stud by a nut 69' which screws upon the. threaded end 59 of said stud. Between the nut and the collar is secured on the stud a leaf spring 70 which bears' at its free end against an arm 71 carrying the stop proper designated-by the numerak 72 and which in this case consists of the end of the arm or carrier 71 bent at right angles thereto and provided on its. under side with a single radial tooth 73 adapted to engage the space between any two teeth of the gear wheel 61 and hold the stop device in'any adjusted position upon said wheel. The heel or root of the Spring 70 is preferably provided with a pin 74 to engage a depression 75 in the collar 5 62 so as to prevent the spring from turning independently of the arm 71'. The stop trivance is provided with a finger p ece 76 to facilitate the operations of adjusting the stop. i fl The spur gear 61 is adapted to mesh with a pinion or toothed gear 77 having a sleeve 78 which is secured by a screw 79 upon the platen shaft so that the wheel 77 turns always with the platen shaft and the laten..

The bar 29 is enlarged near its mid e and 6 formed with an opening at 80 to surround the sleeve 78, the opemng 80 lar e enough to avoid an interference'with-t e back and forth sli ing movements of the bar 29. 0 In Figs. 1 and 2 the'bar 29 carrying the 1 gear 61 is shown in its forward position and p the gear 61 in mesh with the gear 77. When the bar is pushed rearwardly the gear 61 is moved out of mesh-with the gear 77. ,At this time the gear 61 is-as seen at Fig; 12 preferably moved into engagement with a. single tooth or detent 81 fixedlyheld between the head of the shouldered screw 32: and the retaining screw 32, so ,thatfther 0 may. be no accidental rotative movement of the gear 61 wherebyits stops willlo se their, predeterminedrelationship to the gear 77. f a It will be observed that at ,82 there is an puncut tooth in the wheel, or in other words,

the tooth at 82 equals the distance of two teeth and a space which is normally cut between two teeth. This uncut tooth 82 constitutes a stop and what may be terined-ai fixed stop on the wheel 61, the stop 72 being 10c an adjustable and relatively movable stop. Any of the teeth of the wheel 77 constitutes.

a cooperating stop for each of the stops 72 and 82 as will be presently more fully explained. v y a ,Rcferringmore particularly to Figs. 1 and 2 it will be observed that when the platen is rotated either by the knobs or by the line spacing mechanism or otherwise the gear '77 will turn with the'platen and by reason of its mesh with the gear 61, will turn the latter simultaneously, and the. stops 72 and 82 will be carried around in one direction 'or another with the wheel 61 in accordance with r the direction of rotation of the laten. For example, if the platen be rotate forwardly or in the direction of the arrow a the sto 82 will leave the ar wheel 77 and wi travel in the direction of the arrow 6, and

the stop 72 will travel toward the gear wheel 77 until'it is arrested thereby; as indicated -by the dotted lines at Fig. -1. This will in turn arrest the rotation of the gears 61 and 77 and of the platen as well. When the platen. is rotated backwardly or in a' direction opposite that shown by the arrow athe stop 72 will be rotated away from the gear 77 and the sto 82 will be carried toward ,th gear.77 an will finally be arrested by a tooth of said gear as shown Fig 1.

As the stop-72 trave saround toward; the teeth of thewheel'77 of course the stop 82 travels ardundsimilarly but is ineffective duringthis forwardrotatioi of the platen. When; hbwevenfthepla'ten is rotated 'in" the opposite directiomthat is baekwardly; thent e' wheel 61 is rotated in and the stop 82, traveling toward the wheel.

71- until it arrested thereby. If it should be desired toarrestthe platen in its forward: rotationat an earlier period than that pro-.

vided for at Fi 1-, the stop 72. is adjusted ina left-hand ecti'on toward the stop 82 but if it should be-d'esired to-arrest. the platen at a later period than that provided-for .at Fig; ,1 the stop 72 is adjusted around the wheel 61in alright-hand direction. Thesefl adjustments are usually determined bythe printed heading of bills, invoices or the like or'when the mechanism is to be used for oon.

densed record work in' connection with a long sales sheet and whereby a plurality of bills or invoices are to be condensed on said sales sheet. 'The opera-tionHor method of Iperforming condensed record workis so well nown that 'no further explanation seems,

.- to be necessary. In setting said stops for a given heading I prefer first to brin the stop 82 into enga ement with one o the teeth of the wheel 7, as illustrated at Fig.

1, then insert the paper and 'rotate tlie, platen until the first line to be printed is inre 's-.;' ter with the printingpolnt, assuming at t is time that the stop 2 is at a remote rear;

ward point so as not to interfere with this adjustment of the paper. The sto 72' will then'be adjusted by rotatin it in eft-hand direction until it strikes t e teeth of the i wheel 77, as illustrated by the dotted lines backwar at Fi .1. It will be understood of course that m adjusting the paper forwardly for the first rinting line the stop 82 is'rotated d simultaneously and away from the wheel 77. When the stop 72 shall have before itis arre been adjusted as explained then the distance apart of the stops 72 and 82 will-re resent the extent of backward and forwar rota: tions to which the laten may be subjected If desired, numbers orother: indicating marks maybe ap-= plied to coizginpthe vicinity of the-teeth of,

stops-Wiand be set as f arf' tlie iwhe'el 6 1 to facilitate the adjustment of .xwardly as efpre explained,'and at the same time'causingthe stationar tooth 81 to enga'gebetween two teeth 0 the wheel 61 so 75 that the said wheel may not lose its proper .relationsh-ip to the- .wheel 77 when said -'wheels are a in put into'meshbyithe drawing o"ward y of the slide'29, and it may be desired to insert a fresh sheet and continue 80 the condensin of the bi1- on the sales sheet.

It will be observed that'the billing mechanisin is arranged at one side of the earriage,'

j'is compact an occupies but very little room and is not stall in the way- 0 any 'ofthe usualf devices furnished with the machine. vThesedesiderata are accomplished lar ely 1 by the use of the two spur gears arrange in ithesame vertical laneand by-use of the slide bar arranged to be operated trans- 'versely of the carriage or fore and aft of lit-he machine, that -is, to and from the op "orator" It will also be noted that the spur gears may be ofany desired relative sizes,

so that the stops 72 and 82 may make-less or, v more'tha-n a full revolution of the'platen; "The wheels '77 and 61 may be so proportionedthat the mechanism maybe used for a pa e-end 1ock-that' is, means for stopping the orward rotationof the laten when the end ofthe sheet has been reac ed or nearly so;

In the present construction the platen ratchet wheel and the spur gear 77 have thirty-three teeth while "the. spur gear. v61 contains more than-seventy-five teeth, whereby the spur or stop carryin gear 61 is adaptedto more than two reyo utions of the platen. 1 j

If it be desired to stop the rotation of the A I platen in one direction only then one or the other ,of the stops 72 or 82 ma be dispensed with For example, if it be esired to stop the backward rotation of the platen only then the stop .82 alone-will be used, and if it be desired .to stop the forward rotation of 5 the platen-only, then the stop 72alone will be used. I r Various changes may be made without de- I parting from the spirit and scope of myinventio'n.
